APPARATUS FOR SIFTING ASHES.

Specification of Letters Patent.

Patented Feb. I6, JWI5.

Application filed November 11, 1913. Serial No. 800,243.

To all whom it may concern.

Be it known that I, DANIEL J. MURPHY, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Apparatus for Sifting Ashes, of which the following is a specification.

My invention relates to improvements in apparatus for sifting ashes and similar substances, its object being to provide a simple form of device which may be utilized in connection with an ordinary basket and which will be particularly cheap and efficient.

To this end the invention consists in the features of construction, combination, and arrangement of parts hereinafter described and claimed.

In the accompanying drawings forming part of this specification, Figure 1 is an elevation of my improved invention partly broken away; Fig. 2 is a section on line a=w of Fig. 1; and Fig. 3 is an elevation of a modified form partly broken away.

Referring to the drawings, A represents a sheet metal cylinder removably supporting a funnel 2 in its upper end. Secured exteriorly to the cylinder are straps 3 which extend downwardly below the bottom of the cylinder to form legs 4. Supported inside the legs 4 abbve the lower ends thereof is a ring 5 forming a support for the conical sieve 6. The pointed upper end of the sieve 6 thus stands below the opening in the bottom of the funnel 2 as shown in Fig. 1. The lower end of the sifting sieve 6 standing below the lower end of the cylinder leaves an open space between the lower end of the cylinder and sieve as shown.

In use the cylinder may be supported upon an ordinary basket 7 with the ring 5 resting upon the top of the basket and the legs 4 extending downwardly outside the basket. In the preferred form the basket 7 is placed within a larger basket 8, an apron 9 fitted over the cylinder A and extending downwardly loosely over the outer basket 8. The apron 9 may be secured around the cylinder or may slide upon the same to accommodate difierent heights of outer basket. With the parts set up as shown in Fig. 1 the ashes and contained coals will be poured into the funnel 2 dropping therethrough upon the screen 6. The finer ashes will drop through the sieve into the basket 7 and the contained coal will pass downwardly between the sieve and cylinder into the outer basket or receptacle 8. By then lifting the cylinder away from the receptacles the inner receptacle can be removed to allow the ashes being thrown away, and the coal taken out of the outer receptacle.

In Fig. 3 I show a modified form. This form distinguishes from that shown in Fig. 1 by the absence of the outer receptacle 8. In this form I use instead of the outer receptacle 8 an apron 10 depending from the outer edge of the apron 11 corresponding to the apron 9 in Fig. 1. Thus in the modified form the coal instead of passing into the outer receptacle will drop to the ground inside the curtain 10, the curtain 10 preventing the escape of the dust.

I claim as my invention:

1. A sifting apparatus of the class de scribed comprising an open ended cylinder, a funnel carried at the upper extremity thereof, legs carried by and extending below the lower extremity of said cylinder, a conical sieve supported by said legs, the apex thereof being spaced below and on the axis of said funnel, the lower extremity of said sieve being spaced from and defining an opening with the lower extremity of said cylinder.

2. A sifting apparatus of the class described comprising an open ended cylinder, a funnel carried at the upper extremity thereof, legs carried by and extending below the lower extremity of said cylinder, a conical sieve supported by said legs, the apex thereof being spaced below and on the axis of said funnel, the lower extremity of said sieve being spaced from and defining an opening with the lower extremity of said cylinder, and a protector slidably mounted upon said cylinder projecting outwardly and downwardly therefrom and surround ing the opening defined between the said sieve and cylinder.

3. A sifting apparatus comprising an open ended cylinder, legs carried by and projecting below the lower extremity of said cylinder, an inwardly projecting ring carried by said legs spaced a distance below the lower extremity of said cylinder, an upright conical sieve mounted upon said ring and held thereon by said legs, said ring being positioned above the lower extremity of said legs and coacting with said legs to secure the said apparatus to an ash receiving receptacle.

4. A sifting apparatus comprising an open ended cylinder, legs carried by and projecting below the lower extremity of said cylinder, an inwardly projecting ring carried by said legs and spaced a distance below the lower extremity of said cylinder, an upright conical sieve mounted upon said ring and held thereon by said legs, said ring being positioned above the lower extremity of said legs and coacting with said legs to secure the said apparatus to an ash receiving receptacle, and means slidably mounted upon the said cylinder and embracing the lower portion of said cylinder and cooperating therewith for the retention of the products discharged from said sieve.

In testimony whereof I afiix my signature in presence of two witnesses.
